摘要:
This invention describes the process for fabrication of a high conductivity and low resistance solid oxide fuel cell. An anode substrate is mainly prepared via tape casting technique and modified by abrasion and polish process. Electrolyte is fabricated onto the polished side by thin film technologies and can attach well in the cross section. Grinding surface of anode side about 10-30 μm after finish of MEA combination can get a high conductivity and low resistance unit cell and enhance cell performance effectively.

摘要:
A recipe and two sequential processes for fabrication of electrode substrates of solid oxide fuel cells (SOFCs) are described in this invention. The typical recipe consists of 50˜86 wt % electrolyte (8YSZ) or 50˜80 wt % anode electrode (NiO/8YSZ), 12˜22 wt % MEK (solvent 1), 5˜9 wt % EtOH (solvent 2), 1˜2 wt % TEA (dispersant), 0.5˜2 wt % DBP (plasticizer 1), 0.5˜2 wt % PEG (plasticizer 2), 3˜6 wt % PVB (binder), and 0.1˜10 wt % graphite (pore former). Two sequential processes include: 1. The process for preparation of the green tape slurry from materials of the recipe, 2. The synergistic process for fabrication of a high integrity membrane electrode assembly (MEA) of SOFC from the prepared electrode substrates.
